Homeowner wanted an explanation on why master bedroom on the mainfloor was colder than the rest of the home. Master bedroom is colder due to thermostat not being located in the master bedroom and due to lack of supply and return duct work to master bedroom (and high ceilings). Bedroom should have had an additional 8” supply and return added. Due to roof line running any additional ducts will probably not be possible. I recommended having a ductless mini split installed; customer declined due to costs. I also offer to spend time trying to find a way to run more duct (98$ service call fee); homeowner declined. Homeowner signed up for homecare program for both systems and paid first month. I left homecare brochure. No inspection performed.
